/*

|
|
I seem to have found a problem with the $monitor task/events.
|
||
|
|
(this is probably related to bug 399)
|
||
|
|
The problem only seems to arise in vvp mode and not in vvm.
|
||
|
|
Problem: $monitor seems to lose both the first and last time steps.
|
||
|
|
|
||
|
|
A complete copy of the run follows with source appended at the end.
|
||
|
|
(The correct output from vvm is shown in the last run)
|
||
|
|
This file compiles and produces the problem.
